The mobile web and your personal information

James Rosewell writes:

The mobile techie community has known about mobile networks and indeed some handsets providing unique information about mobile devices and customers for a long time. Collin Mulliner, a graduate student at the Technische Universitat Berlin, has recently bought the issue to the attention of the public during a talk at the CanSecWest conference in Vancouver.

Information such as IMEI and Mobile Phone Number is passed to web servers accessed by a mobile device or Mobile Network Operator (MNO) proxy server in hidden fields called HTTP Headers. The amount of information, format and ultimately usability of the information varies between MNO and mobile device. Practically, the inconsistency of the information makes it of little practical use to web sites. The apparent random nature of the information provided indicates MNOs haven’t really thought through how they’re configuring their gateways and proxies.

The following table shows the HTTP Header (hidden fields) provided by a mobile request received at thefonecast.com yesterday. Notice the x-up-calling-line-id field that contains the mobile number of the requesting device. (We've removed the mobile number from this example). This particular request was provided via the ZXWAP Gateway from ZTE.

x-up-calling-line-id
XXXXXXXXXX

The real point is that MNOs are seen to be taking liberties with customers personal information. There are many practical uses to providing this personal information “behind the scenes”. For example:

·    A web site that requests a telephone number can default the telephone number field to the mobile number provided by the mobile network reducing the amount of data the user needs to enter.

·    Multiple interactions can be related to one another without requiring explicit authentication.

On a darker note, once a malicious web site has a mobile number, the text message inbox would become the next target for spam.

Many people will be unhappy with this personal information being provided without consent. MNOs need to establish a clear and consistent policy around the dissemination of such information and ensure customers are in control of the personal information their mobile phone is giving out.

CES Unveiled at London: the future's looking pretty bright

Mark Bridge writes:

The 2012 International CES is expected to be the world’s largest consumer technology tradeshow. It runs from 10th to the 13th of January in Las Vegas next year and will contain technology from more than 2,700 companies spread over a record-breaking 1.8 million square feet of exhibition space.

Yesterday I saw a preview of what’s expected there – and all without leaving the UK. Instead I headed to a conference centre where the first-ever ‘CES Unveiled at London’ event took place.

Flash is dead, HTML5 is the future. Okay, the next stage in the evolution of the mobile browser isn’t that clear – but a restructure at Adobe has pretty much marked the end of mobile Flash development.

McAfee's top five tips for avoiding malicious mobile apps

Mark Bridge writes:

Mobile security - as I’ve said several times in the last few months - is becoming a hot topic. Although the number of mobile viruses and malicious applications is relatively small when compared with attacks on PCs, it’s on the increase.

Last week we talked to Eddy Willems, Security Evangelist at G Data, about the security risks facing smartphone users... and in the last 12 months we’ve also spoken to David Emm of Kaspersky Lab UK and Craig Heath from Franklin Heath about similar subjects.

One day, every phone will be smart - and every tablet will be super

Mark Bridge writes:

We’ve previously talked on The Fonecast about ‘superphones’ - a relatively arbitrary description for high-end smartphones. Google described its Nexus One as a superphone when it was launched at the beginning of 2010 - although it’s also what Dr Who’s companion called her upgraded Nokia 3200 in 2005.

Now Strategy Analytics has a definition and a growth forecast.
